We are all armchair guessing
I am sure Cirrus have the actual figures of a descent under the chute in still air onto a flat unobstructed surface as well as the shock loading not G forces onto the avionics.
G forces are irrelevant its abrupt shock loading which is relevant!
Obviously conditions and surface will have a major impact (excuse the pun)
Ie with 30 kt winds on the surface and into the side of a building, hitting trees, lampposts, power cables or steep sided terrain or even into water will change the whole outlook on such a landing both in terms of avionics and occupants!
Into water the avionics are buggered anyway
I know what flying a vibrating Mooney with a slightly bent prop did to the avionics in our group aircraft! Buggered them!
